Evaxion Biotech A/S announced positive preclinical data for its cytomegalovirus (CMV) vaccine program, EVX-V1, on November 12, 2024. The data, presented at the 9th International Conference on Vaccines Research & Development, showed that antigens identified by Evaxion’s AI-Immunology platform effectively triggered targeted immune responses, including both CMV reactive B and T cells.

The company also designed a proprietary prefusion gB antigen, a known CMV vaccine component, which successfully induced a specific immune response comparable to that of the conventional gB antigen. Evaxion plans to combine these AI-Immunology identified antigens with its proprietary prefusion gB antigen in a future vaccine candidate.

This novel multi-target approach aims to enhance vaccine efficacy by combating the virus from numerous angles, differentiating it from traditional methods that focus on a limited set of glycoproteins. The data brings Evaxion closer to developing an effective CMV vaccine, a disease for which no approved vaccine currently exists.
